DG453EQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG453EQ-T1-E3 is a high voltage quad SPST CMOS analog switch in a 16-pin TSSOP package. It features two normally closed and two normally open switches with a typical on-resistance of 4 Ω and maximum of 5.3 Ω at ±15 V. The device supports dual supplies from ±5 V to ±15 V or a single supply up to 12 V, with an absolute maximum rating of 44 V between V+ and V-. Key dynamic parameters include a turn-on time of 80 ns (typical) and turn-off time of 60 ns (typical). It operates within a temperature range of -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix EQ-T1-E3 against the manufacturer's ordering information to confirm the 16-pin TSSOP package and extended temperature range. Ensure that the RoHS compliance status matches current regulatory requirements for your region. Cross-reference the part number with official Vishay documentation to validate availability and lifecycle status before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed channels is required within a single package. The DG453 is pin-compatible with the DG411, DG412, and DG413 series, allowing for potential design upgrades. Consider the 5.3 Ω maximum on-resistance and 100 mA continuous current capability to ensure suitability for the intended load conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG451/DG452/DG453 family of high voltage analog switches. The DG453 variant specifically provides two NC and two NO switches, distinguishing it from the DG451 (all NC) and DG452 (all NO). All three variants share identical electrical characteristics and pinouts, facilitating flexible system design using a common footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG453EQ-T1-E3 is pin-compatible with the DG413EY-T1-E3 and DG413EQ-T1-E3. Verify that the alternative part meets the same voltage and resistance specifications if substituting in an existing design.
